I once had a civil argument with [someone], in which I laid out my position in the usual way: “Premiss + premiss + premiss = conclusion.” She responded: “Well, that’s your opinion; you have yours, and I have mine.” I pointed out that no, I wasn’t asserting an opinion, I was making an argument based on facts and logic. Either my facts are wrong, or my logic is. She looked at me like I had lost my mind.
